to start the JBoss:-extract "jboss-5.1.0.GA.zip" to some directory.-call "bin\run.bat" or the script for your OS.

To use JBoss in Eclipse, you need a plugin. You could either use the "Web Tools Platform" plugin 3.1.1, or the "JBoss Tools" plugin (the latter I don't know).

Take a look at the Eclipse help to find out how to configure it for Web Tools Platform plugin. See http://help.eclipse.org/galileo/index.jsp (one the left side, browse to "Web Tools Platform user guide" => "Using the server tools".

One more thing. I noticed you wrote that you downloaded jboss-5.1.0.GA.zip. That download is for use with JDK 1.5, but you are using JDK 6. Go back to the downloads page and get jboss-5.1.0.GA-jdk6.zip - that one is for use with JDK 6.

i am just configuration Jboss to run on eclipse and update Jboss tool for eclipse . But i can not create project with seam 1.2 from eclipse updating when new project is create . look like i miss seam runtime ?

I have not used JBoss Developer Studio (JDS) 2.1 Portfolio Edition, so I cannot say which one is better.

It is my understanding that JDS is geared towards building applications with the corresponding JBoss Enterprise Application Platform (EAP). Thus if you want to use EAP and a development environment that has tight integration with it, then use JDS. Whihc means you are stuck using that version fo EAP, and thus the version of JBoss AS on which is is based.

If you want to use the latest and greatest version of JBoss AS, stick with the latest Eclipse and the latest JBoss Tools.
